    Summary
    This summary is machine-generated.

    Round atelectasis, a peripheral pulmonary collapse, can mimic tumors. Characteristic imaging and negative biopsies confirm this benign condition, avoiding unnecessary surgeries.

    Area of Science:

    • Pulmonary Medicine
    • Radiology
    • Thoracic Surgery

    Background:

    • Round atelectasis is an uncommon form of pulmonary collapse.
    • It often presents as a peripheral, pleural-based mass, mimicking lung cancer.
    • It is typically a sequela of pleural effusion.

    Purpose of the Study:

    • To discuss the pathogenesis, clinical, and radiological features of round atelectasis.
    • To present experiences with 11 patients diagnosed with round atelectasis.
    • To highlight diagnostic strategies to avoid unnecessary surgical intervention.

    Main Methods:

    • Review of 11 patient cases with round atelectasis.
    • Analysis of clinical and radiological findings.
    • Correlation of imaging features with surgical diagnosis or long-term follow-up.

    Main Results:

    • Round atelectasis presented as a well-demarcated, round or oval, intrapulmonary mass.
    • Diagnosis was confirmed surgically in 4 patients and by long-term follow-up in 7.
    • Characteristic radiographic features coupled with negative fine-needle biopsy were key to diagnosis.

    Conclusions:

    • Round atelectasis is a benign condition that can be confidently diagnosed non-invasively.
    • Characteristic imaging features are crucial for differentiating it from neoplastic lesions.
    • Accurate diagnosis prevents unnecessary thoracotomy and pulmonary resection.
